- 11 x 0-5V analog inputs with redundancy for electronic throttle and switchable 5V pullup
- Trigger and home inputs with differential inputs, adjustable thresholds and glitch filters
- 6 x synchronous pulsed inputs, zero crossing or adjustable thresholds - cam sensor inputs, frequency inputs or 0-5V analog inputs
- 1 x on-board wideband controller, supporting NTK and LSU4.9
- 1 x on-board 4 bar MAP sensor
- 2 x CAN ports with switchable termination
- Onboard data logging - Up to 300 channels of logging at sample rates up to 1ms (1kHz) with 128MB of internal memory
HARNESS OVERVIEW
Ideal for modified street cars, engine swaps and custom wiring jobs. The Universal Wire-in Harness has a set of ECU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are colour coded and clearly labelled. Connect your Haltech ECU to the terminated end and follow your wiring diagram for all the engine connections. Load your base map and you're ready to go!
- Colour coded and labelled wires that match the detailed wiring diagram for a confusion free construction process.
- The wiring diagram is accompanied by the quick start guide and software is downloadable from the Haltech Website.
